ANTISLIPPING OVERSHOE FOR HORSES.

Specification of Letters Patent.

Application filed December 18, 1911. Serial No. 666,385.

To all whom it may concern 'Be it known that I, ARLINGTON L. HAR- nIsTY,a citizen of the United States, re-

siding at Silver Spring, in the county of Montgomery and State ofMaryland, have inve'ntedcertain new and useful Improvements inAntislipping Overshoes for Horses,

of which the following is a specification.

My invention relates to overshoes for horses of that kind which aredesigned to be detachably applied to the ordinary horse shoe nailed onthe horses'hoof, for the pur pose of providing an easy and, quicklyapplied anti-slipping attachment, or for holding any other form ofattachment to the shoe on the horses hoof. It is an improvethe servicesof'a blacksmith, as will be herement upon that form of such overshoeswhich is made in two hinged sections adapted to be expanded orcontracted to suit the 20 varying sizes or shapes of horse shoes, andwhich are secured by fastening devices which engage with the horseshoealready on the horses hoof. My improvement consists in the novel formand construction of the overshoe and novel means for connecting it tothe horseshoe in a simple, convenient and practical way, which is notliable to become loose or detached and which may be applied by thedriver or anybody else, without requiring inafter more fully describedwith reference to thedra-wing in which Figure l, is a top plan view ofthe usual horseshoe with'my invention shown applied to the underside ofthe same, a part of the horseshoe being broken away. Fig. 2, is a View"of the same parts, the view being taken from the underside next to theground. Fig. '3, is a vertical longitudinal section of the same parts.and also through fajfportion of the horses hoof. 'Fig. 4, is a cross'section taken through the line 44 of Fig. 1,-beside one of the holdingbolts.

Fi 5 isa detail of the locking washer -of tl i e holding bolts and, Fig.6, is a detail showing a slight modification. Similar letters ofreference indicate-the same parts in all the views. 1

In the drawing A represents the ordinary horseshoe as nailed upon thehorses hoof in the usual way, plied. I B B represent the two halves ofmy overshoe, which are made substantially alike and which are hingedtogether near the toe to which my overshoe is appart at b, so as topermit them to be expanded or drawn together to fit the varying sizesand forms of horseshoe found on different horses or mules. The hingedovershoe sections are each of unitary character, that is to say, aremade in one piece extending substantially from toe to heel of thehorseshoe. 3

Each overshoe section is made by drop forging or casting from steel andis formed along its outer edge with two upwardly extending lips orflanges C and D. The forward one of these, C, is arranged near the toeand extends upwardly a greater distance than the rear one, so as toextend 51p not only above the outer edge of the shoe, but also somedistance up along .the front surface of the horses hoof and it is cantedslightly inwardly at the top and is made thin enough to permit it to bestill further bent inwardly, by a blow from a hammer, to cause it tomore tightly fit against and closely hug the outer anglexof the horseshoof, which varies somewhat in different horses. The other upwardlyextending flange, D, is situated at or near the rear of the overshoe-andis arranged to hug and closely fit the outer ed e of the rear portion ofthe shoe. This flange is also slightly canted inwardly. v

To hold the two hinged sections of the overshoe tightly and rigidly tothe horseshoe, so that they cannot become disconnected therefrom, thereis a toe locking member E and two heel locking bolts F F, one bolt oneach side, and all of these locking devices are on the inside portionsof the overshoe -and are adapted to overlap and engage the upper insideedge of the horseshoe.

When the overshoe is applied exteriorly to the shoe on the horses hoof,the two sections of the overshoe are pressed inwardly toward each otheruntil "the two exterior flanges, C, D, on eachside, are solidly againstthe outside edge 'of the shoe and horses hoof and then the toe lockingmem-- ber E and heel locking bolts F F are adjusted to the inside edgesof the horses shoe and, by means of an overlapping flange e on the toelock and an overlapping flange f on the head of each bolt, the lockingdevices engage the upper surface of the inside edge of the shoe andprevent the overshoe from coming off. These locking devices are of.

special and important construction, which I ferred to. Through the toelocking member E there extends a screw threaded hole into which isinserted the screw threaded end of a headed bolt E whose shank extendsthrough larger slots in the lapped edges of I the inner wings of theovershoe sections and this bolt has a rigid head on the lower side nextto the ground and between the head and the faces of the wings of theovershoe sections there is interposed a washer E The face of this washerwhere it engages .the face of the wings of the overshoe sectill tions,and. also the outer faces of the wings themselves, are serrated withinterlocking corrugations, as seen at m Fig. 2, so that said washer andbolt when tightened up cannot slip to the rear. In like manner the headof the bolt itself, and the washer, may have interlocking serrations, asseen at @1, so that the bolt cannot turn. The toe locking mem ber E isalso formed with an offsetting rigid arm 6 Fig. 1, whose end is bentdown at right angles and is extended through a curved slot 0* in thewing of the overshoe section, and on the outer side has a head 6 Thisoffsetting arm in the slot 6 helps to hold and guide the locking memberin its adjustment and holds itin place against accidental loosening.

In. each inner wing portion of the over shoe section is formed a curvedslot G and the inner edge of such curved slot is reinforced or made muchthicker vertically, as shown at 0, than the body portion of the overshoeonwhich the shoe rests. Through such slot on each side there passes alocking bolt F whose head has the overlapping flange f engaging theinner edge of the shoe and extending above the same and projectingoutwardly between the shallow space between the shoe and the horseshoof. These bolts have each a nut (Z on its lower end below the body ofthe overshoe and between said nut and the body of the overshoe is awasher to of special construction as seen in Figs. iand 5. Such washeron the side next to the overshoe is of a somewhat wedge shape andpenetrates the slot whose edges are beveled and serrated as seen in Fig.2, the wedge shaped washer being also serrated, so that when the washeris forced into the slot and held there by the nut, the serrations on thewasher interlock with those along the edges of the slot. and prevent thebolt from sliding longitudinally in the slot. The head of the bolt F issquare in cross secaway from its overlapping position above the shoe,and second as the thickened reinforced portion 0 is above the plane ofthe overshoe body and near the top of the bolt it forms a solid backbearing for the bolt head at its upper end to hold it more strongly uptoits locking position against the inner edge of the horse shoe. The slotsG G, which form seats for the bolts, are arranged in longitudinalposition in relation to the sides of the overshoe sections and at anangle to the longitudinal axis of the shoe, which angle may vary indegree, so long as one end of said slot is closer to the inner edge ofthe shoe than the other end.

The slots G G approach each other at their forward ends and they alsoserve a double purpose in that they allow the bolts to be adjustedforward and backward to suit the size or shape of the shoe and alsoadapt my invention to shoes which have a greater or less cross sectionalwidth. This together with the hinged character of the overshoe sectionsadapts the device to all sizes, forms and shapes of shoes. Furthermoreit will be seen that these bolts are adapted. to thin or thick shoes, orshoes hal tg 'yvorn out, as in form of the overshoc sections there isformed in each half a crease or fuller g, see Fig. 1, which coincidesexactly with the outside nail crease of the horseshoe and which creasegis designed to receive the projecting nail heads of new shoes, so thatmy overshoe may fit flatly against the lower face of the horseshoe ifthe nail heads of the latter'should not be worn off.

In my invention the lower faceio f over-shoe is to be provided with toean heel calks h 7: and these may be either formed permanently on theovershoe, or be detachable therefrom by any of the well known methods.At the toe portion of-gthe overshoe sections there are two rigid lugs ZZ,'arranged transversely to the line of rail travel, which give asuilicient thickness fbr a strong pivotal connection for the hingedover-shoe sections and also a suficient body of material to hold thepermanent or detachable toe ealks whi h are'apnlied thereto As amodification of my invention, Imay, instead of usinga slot G, employsimply a series of holes G in the overshoe, see Fig. 6, through whichthe bolts pass and in any one of which the bolts may be adjusted, but

I prefer the continuous slot, as it permits.

the bolts to be more quickly fitted to their locking position Withouttaking the bolt out and fitting it into another hole.

itwil be seen that my overshoe is a little short of the toe of the shoeand also a little short of the heels, so that when applied to shoes thathave rough shod toes or heels, the roughened toe of the'shoe willproject down in front of my overshoe and the roughened heels willproject down in rear of my overshoe.
